Pierzynski, who was placed on the 15-day disabled list on Tuesday (retroactive to Aug. 13) with a fractured left thumb, said he's still planning to return on Sept. 1 when rosters expand.
"I'm not rushing it, because Sept. 1 is the day and it's still two weeks away," he said. "There's lots of time to get some work done. It's not like we have to get something done right away, so we're taking it slow and going from there."
Pierzynski said live catching should be added into his workout routine in a day or two, and he will start hitting off a tee soon.
"The biggest thing is that we did a bunch of stuff [Thursday] and there were no residual effects [on Friday]," Pierzynski said. "There was no new pain, there was no new soreness, there was no crunching and creaking in there, which is what they worried about when I started doing stuff. There was none of that, so hopefully we'll get more treatment after BP and we'll see how it feels [on Saturday]."
